R. A. GOODYEAR, OF NEW HAVEN, CONNECTICUT.

IMPROVEMENT IN LAMPS.

Specification forming part of Letters Patent N0. 55,280, dated June 5, 1866.

To all whom it may concern:

Beit known that I, ROBERT A. GOODYEAR, of New Haven,,in the county of New Haven and State of Connecticut, have iuventedcertain new and useful Improvements in Coal-Oil Lamps; and I hereby declare the following to be a full, clear. and exact description of the same, reference being had to the accompanying drawing, which represents, in section, a coal-oil lam p-burner constructed in accordance with my invention.

It is well known in using the ordinary coaloil lamp that the fluid in the lamp, notwithstanding every precaution and measure taken to preventit, will ooze through the joint of the burner and run down'the sides of the lamp, collecting in such quantity as to make it very disagreeable to handle the lamp. This oozing of the oil takes place principally at the junction of the burner with the cap or cover of the vessel or fluid reservoir, and at the points where the shaft which carries the pinion for raising or lowering the wick pierces the sides of the burner.

Although this defectin coal-oil lamps has not as yet been remedied, yet the disagreeable consequences attending it may be in a great degree obviated by collecting the oil in some kind of receiver near the points where it oozes from the burner, and so preventing it from running down and spreading over the sides of the lamp.

The object of my invention is to accomplish this result, and I do this by means of a very simple yet efficient contrivance.

I make the metal cap which covers the fluid vessel or reservoir, and to which the burner is attached, with an annular cup-like flange or dish around that part of it which fits around the sides of the lamp. This annular flange or dish may be either shaped from a separate piece of metal and then soldered to the cap, or it may be simply a continuation of the same piece of metal which forms the cap. The oil running down from the joints of the burner, through which it has oozed, is caught in this annular dish, which encircles the neck of the lamp, and is thus prevented from spreading over sides of the lamp.

To enable those skilled in the art to understand and use my invention, I will now proceed to describe it by reference to the drawing which accompanies and forms part of this specification.

B is the burner of a coal-oil lamp, which is fitted to and screwed in the cap D, as seen at b. This cap fits over the top of the glass reservoir or vessel C.

To the base of the cap is secured the annular dish A, formed as above described. The oil, which oozes from thejoints band the points a, where the shaft F is inserted in the burner, runs down the sides of the burner and is caught in the dish A, which prevents its further flow downward. The lamp is thus kept clean and free from all traces of oil.

I am aware that M. B. Dyott has a drip-cup similar in form and position to mine; but

What I claim as an article of manufacture The construction of the drip-cup attached to the metal cap which covers the fluid "essel or reservoir, as and for the purpose shown and described.

In testimony whereof I have signed my name to this specification before two subscribing witnesses.

R. A. GOODYEAR.
